AI Technical Summary

Benefits of technology

The present invention relates to a process for preparing an oil soluble additive composition by reacting a molybdenum component with an imide derived from the reaction product of a hydrocarbyl dicarboxylic acid component and a polyamine component. The resulting composition is then post-treated with a post-treating agent. This process produces a post-treated molybdated succinimide additive composition that can be used to improve the performance and properties of lubricating oil compositions. The resulting lubricating oil composition has improved viscosity, low-temperature properties, and anti-corrosive properties.

Problems solved by technology

However, one of the major detriments to using finely ground molybdenum disulfide is its lack of solubility.

example 2

[0076]125 g of molybdated succinimide, which was prepared according to Comparative Example 1, was allowed to heat up to 165° C. After reaching 165° C., 11 g (2 moles of EC per basic nitrogen) of ethylene carbonate (EC) was charged slowly over the duration of 1 hour. After charging the ethylene carbonate, the reaction was allowed to hold at 165° C. for an additional 2 hours until all EC was reacted as monitored by IR spectroscopy with final Mo content=4.1 wt %.

example 3

[0077]108 g of molybdated succinimide as prepared according to Comparative Example 1, was allowed to heat up to 165° C. After reaching 165° C., 13 g (2 moles of glycerine carbonate per basic nitrogen) of glycerine carbonate (GC) was charged slowly over the duration of 1 hour. After that, the reaction was allowed to hold at 165° C. for an additional 2-2.5 hours until all GC was reacted as monitored by IR spectroscopy with final Mo content=4.0 wt %.

example 4

[0078]In a 3-neck 500 mL glass reactor equipped with a temperature controller, mechanical stirrer and water cooled condenser, 245.31 g of a succinimide having a TBN of 171 mg of KOH / g of sample, prepared from a hexadecenyl succinic anhydride (HDSA) and diethylenetriamine (DETA) at a molar ratio of DETA to HDSA of 0.9:1, was charged. The reaction mixture was allowed to heat up to 165° C. After reaching 165° C., 65.83 g of ethylene carbonate was charged slowly over the duration of 1 hour. After charging the ethylene carbonate, the reaction was allowed to hold at 165° C. for an additional 2 hours and monitored by IR and the TBN of the resulting solution was measured to be 59 mg of KOH / g of sample.

Abstract

The invention is directed to an oil soluble additive composition prepared by a process comprising reacting a molybdenum component; an imide derived from the reaction product of a hydrocarbyl dicarboxylic acid component and a polyamine component wherein the hydrocarbyl dicarboxylic acid component is the reaction product of a dicarboxylic acid component and a hydrocarbyl component; and a post-treating agent, thereby producing a post-treated molybdated succinimide additive composition.

Description

FIELD OF THE INVENTION[0001]This invention relates to new lubricating oil additives and lubricating oil compositions. More specifically, it relates to new lubricating oil compositions containing a friction reducing component comprising a molybdenum compound and alkyl or alkenyl imide.BACKGROUND OF THE INVENTION[0002]Molybdenum disulfide has long been known as a desirable additive for use in lubricating oil compositions. Molybdenum disulfide is ordinarily finely ground and then dispersed in the lubricating oil composition to impart friction modifying and antiwear properties. However, one of the major detriments to using finely ground molybdenum disulfide is its lack of solubility.[0003]As an alternative to using finely ground molybdenum disulfide as a friction modifier, a number of other approaches involving various salts of molybdenum compounds have been employed. Molybdenum dithiocarbamates (MoDTC) and molybdenum dithiophosphates (MoDTP) are well known in the art to impart friction...
